Wicked Was this a good idea? (2006 525 EXC)

Might be a little late to ask



Picked up a 2006 525 EXC this weekend to compliment my fantastic 990 streetbike. I made it about 65 pages into this thread before I figured it might be a really bad (good idea).

Paid $2700, it has 350hrs/5500 miles. Looking to rip around in a few parks around the Seattle area this summer and then maybe do some longer trips.

First Impression: Wheelie city. This thing is NOT like my DRZ400 was. And after taking an hour to change the oil, I definitely realize its not my DRZ.

Here are my takeaways from that megathread:

-Fan kit: Necessary
-Oil Cooler / Cush Hub: Only needed for extended highway riding
-Steering Damper: Good idea but not necessary

Maintenance Plan:

Oil (done)
Valves/Plug/Coolant (to be done tonight)
Repack exhaust
Make it streetlegalish (its plated already)
Freshen forks, possibly the shock as well, might need a respring (I'm 200lb)

Ride? Am I OK to assume that until it starts to run worse the top/bottom end should be happy? Or should I pull it apart to check everything?

Thanks guys!

do you know if it's had any work done to it?
if not, you're probably looking at the valves running out of adjustment, and it may be time for a piston / bore check (they oval)
fortunately, you have one of the masters fairly local. (djh)

I'm gonna check/adjust the valves tonight. There's a pair of valves in a spares box so I'm assuming they were replaced at some point.

Is the ovaling of the piston just cause lower power, or other issues? After my DRZ I'm not worried about it being too slow

the piston doesn't go oval, the bore does. think hard nikasil over relatively soft aluminum cylinder.

i believe you'll start burning oil and losing compression when it's on it's last legs.

fwiw, ktmtalk RFS forum is a really good place for the nuts and bolts type of info.

and DJH is in kirkland iirc, for when you need stuff.

OK in that case I'll check the compression. Doesn't smoke so don't think it's burning any oil.

I have a 06 525XC. it has 270+ hours and still runs great, I bought it last year and there was 168 hours on it. PO checked the valves right before I bought it and they were fine. I checked them a while back and still good. My water pump seal is starting to to dampen the cylinder so one is on order, it didn't fail yet. I came off of a xr4 and this bike out performs it by far. Yes it may need more maintenance but it is worth it. I don't believe the oil changes are that bad. Have fun.

i gotta '06 SMR 450 that i've dirtyfied.... the more i mess w/that RFS motor, the more i like it..... baddazz motor.....change the oil, adjust the valves, good air filter, and if it ain't doin' anything weird, ride it....all the dorks act like adjusting the valves is rocket science... really?.... how big a carb is it? 39 or 41mm?.... put in an OCEMP needle if it ain't got one, get the accelerator pump firing right.... that DJH guy is the carb god at KTMTalk, so if he was close to me, i'd definitely make a friend, there's alotta carb voodoo.... fat is where it's at, runs alot cooler.... get the right springs for your weight, big dealio, the rear sag is huge, and dialing up a too soft spring ain't it...... gotta get the rear sag right, 35mm static, manual sez 95-105mm rider, alotta people say 110-115mm rider, so YMMV... and set it standing.... i ride in sugar sand in fla, so what you got up there is probably pretty different, and you can run less rear.... fukkin' cool bike, i really want that wide ratio gear box that you got....

DRZ?.... hahahaha

I Believe its an FCR39. JD Jet kit installed already, not sure what jets are in there yet but I'll check this week.

Glad you said just run it if it's not doing anything funny. I wanna ride not rebuild!

OK so spent some time wrenching on this beast last night. As I stated before, it has 350hrs/5500 miles.

In the spares box I found a bearing (new) which I identified as a camshaft bearing. I also found a piston ring compressor, and 2 old intake valves.

I think it's safe to say that the engine has been apart and serviced? Is there a way to tell if I have new SS valves with just the cover off? When checking the piston/cyl, would they always install new rings?

Thanks!
